THE BULL-FROG. 
It is thought by many persons to rank among the handsomest of the froggish tribe. The 
general color is light golden-green, variegated with four rows of olive spots, edged with rich 
gold. One regular row of these spots runs along each side of the spine, and the others are 
scattered rather vaguely along the sides. The throat is white with a silvery lustre, and the 
abdomen whitish-yellow. The aural vesicles are brown, with a circular centre of azure-blue, 
and look like two little targets on the side of the head. The eyes are very large, of a beauti- 
ful golden lustre, and with a bold black streak drawn horizontally through their centre. The 
legs are exceedingly long in proportion to the size of the body, being five inches in length, 
whereas the body measures scarcely three inches. This length of limb and lightness of body 
adds greatly to the leaping powers, for which this creature is so celebrated. 
The Shad-Frog is called also the Leopard Frog, as well as Shad-Frog in Pennsylvania. It 
inhabits North America generally. 
The Green Frog {liana clamitans ), called also Spring Frog, inhabits the United States 
east of the Rocky Mountains. It is a handsome species — bright green, spotted with black. 
The Wood Frog {liana temporaria ) is a European species, common in all eastern 
portions of the United States. Two varieties are recognized. 
The Solitary Spade-foot ( Bcaphiopus ) is a curious form, inhabiting sparsely the eastern 
United States. 
The common Tree Toad ( Hyla versicolor ) is very abundant and familiar in the eastern 
Middle States. Its length is about two inches. H. picker ingii , Pickering’s Frog, is less 
common. H andersonii , Anderson’s Frog, is quite rare. Pickering’s is about one inch 
in length. 
The Tree Frog ( ChoropMlus triseriatus ) inhabits the eastern portion of the United 
States. 
The Cricket Frog {Acris gryllus ) has the same habitat. A variety, crepetans , is 
enumerated as a North American form — called the Western Cricket. 
Another very common and very pretty Frog is abundant in the eastern United States. 
This is the Pickerel Frog, so called because it enjoys a sad pre-eminence among anglers as a 
bait for pike, too fortunate if it can be snapped up at once by the voracious fish, instead of 
dangling for a season in mid-water, with a hook delicately inserted under its skin so as to 
keep it lively as long as possible, and prevent it from losing by death its attractive 
appearance. 
It is mostly found in or near the salt marshes, and is remarkable for possessing a 
powerful and extremely disagreeable odor. In spite, however, of this seeming draw- 
back, its flesh is said to be very delicate, and to be quite as good as that of the edible 
Frog of Europe. 
The coloring of this species is very striking, on account of its irregularly squared aspect. 
The ground tint is pale brown above, covered with moderately large square spots of dark 
brown arranged like the stones of a tesselated pavement, and producing a somewhat regular 
pattern. A bright yellow line, not raised above the general surface, runs from behind each 
eye, and the under parts are yellowish-white. It is quite a little Frog, being under three 
inches in length. 
Upon the accompanying oleograph is presented the figure of the celebrated Bull-Frog of 
America {liana catesbiana ), one of the largest and most conspicuous of its kind. 
This enormous batrachian is perhaps the best swimmer among the Frog race, having been 
known to live for several years in water without any support for its feet. It leads a solitary
